iSCSI Configuration Overview
Before you can begin to back up and restore data with the RDX QuikStation 4, the
host computers (initiators) must establish an iSCSI connection to the RDX
QuikStation 4’s storage targets.
To establish an iSCSI connection, you need to have iSCSI initiator software installed
on the host. Verify that the host computer OS has iSCSI initiator software installed
(see
page 6 ).
Depending on how you configured the logical device type for the RDX QuikStation 4
(see
“Selecting the Logical Device Type” on page 60 ), you will have one to four
iSCSI targets to connect.
Note: For more information about viewing iSCSI targets, see “iSCSI Device
Overview” on page 71 .
You can configure iSCSI initiators with or without iSCSI security. The RDX
QuikStation 4 supports one-way Challenge Handshake Authentication Protocol
(CHAP). CHAP is a protocol that is used to authenticate iSCSI connections and is
based upon the initiator and target sharing a
secret (a security key that is similar to a
password).
With one-way CHAP authentication, the iSCSI target (storage device) authenticates
the initiator (host). The secret is set just for the target. All initiators that want to access
that target need to use the same secret to connect to the target. For more information,
see
“Set iSCSI Security” on page 27 .

You can add up to 10 initiator users (CHAP
authentication) or hosts (host
authentication) to each iSCSI target. One active user or host connection is
allowed at a time for each iSCSI target.
